* 20-notes: Notes Vue 组件化测试
|
||||
*
|
||||
* 覆盖功能点：
|
||||
* 初始化 — 默认笔记、首条选中、侧边栏/编辑区结构
|
||||
* 列表 — titleOf/previewOf、按更新时间排序
|
||||
* 搜索 — 关键字过滤、无结果状态、空搜索恢复全量
|
||||
* 选择 — 点击切换、编辑器同步内容、日期显示
|
||||
* 新建 — 新增空笔记、自动选中、持久化
|
||||
* 编辑 — 输入更新 body/updated、自动保存
|
||||
* 删除 — 确认后移除、无笔记时编辑器禁用
|
||||
* win.appState — add/remove/cur 暴露给菜单
|
||||
* 卸载 — DOM 清理
